'fruit' is the definition.
(I've seen this before)

'winner taking road back over lump' is the wordplay.
'winner' becomes 'victor' (synonyms).
'taking road back over' becomes 'ia' (I can't explain this - if you can you should give a lot more credence to this answer).
'lump' becomes 'plum' (I have seen 'Lump of fruit ' mean 'plum' so perhaps 'lump' could also mean 'plum').
'victor'+'ia'+'plum'='VICTORIA PLUM'

'of' acts as a link.

Can you help me to learn more?
